2.8. U-Boot environment filesystem

barebox supports accessing U-Boot environment contents as a regular filesystems in both read and write modes. U-Boot environment data (ubootvar) device supports automount, so no explicit mount command should be necessary and accessing the environment should be as easy as:

barebox:/ ls -l /mnt/ubootvar0

However the filesystem can be explicitly mounted with the following command:

barebox:/ mount -t ubootvarfs /dev/device /mnt/path

NOTE Current implementation of the filesystem driver uses lazy synchronization, any changes made to the environment will not be written to the medium until the filesystem is unmounted (will happen automatically on Barebox shutdown)
